TO ALL WHOM IT MAY CONCERN: i

Be it known that I, THOMAS BISBING, of Buckstown, in the county ofSomerset, and State of"Pennsylvania, have invented anew and usefulImprovement in Churn; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, referonce being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a vertical section of my improved churn taken through theline a: z, iig. 2.

Figure 2 is a top view of the same.

Similar letters of reference indicate like parts.

My invention has for it object to furnish an improved churn,conveniently and easily operated, and which will do its work quickly andthoroughly; and it consists'in the construction of the dasher,'and inthe combina'- tiouof the removable frame, sliding frame, ratchet-bar,and pinion-wheel with each other, with the body of the churn, and withthe dasher-shaft; the whole being constructed and arranged ashereinafter more fully described.

A is the body of the churn, which, if made square, should have itsangles filled with triangular blocks, so as Vto bring the milk morefully under the action of the reciprocating dasher. B is a frame fittedupon and removably attached to the top of the churn-body A, or of theframe by which the said churn-body is supported. Upon the inner sides ofthe side bars of the frame B, are formed horizontal grooves, in whichthe frame C slides back and forth. To the frame C, near one end,ispivoted the end of the connecting-rod D, the other end of which ispivoted to a crank formed upon the crank-shaft E, which revolves inbea-rings in the frame B, and to which motion is given by means of thecrank F. Or, if desired, motion may be communicated to the slidinglframe C by means of a lever. G is a ratchet-bur attached to the slidingframe C in such a position that its teeth may mesh into the teeth of thepinion-wheel I-I, attached to the end of the flasher-shaft I, so as tocommunicate to the said shaft a reciprocating rotary motion, as thesliding frame is moved back and forth. The lower end of the dasher-shaftI is pivoted to the centre of the bottom of the churn, and its upper endpasses up 'through the cover J, and is pivoted to a cross-bar of theframe B. K are the dasber-blhades which project radially from oppositesides of the shaftI, and should be so arranged that the verticaldistance between each pair of arms or blades may be about equal to thevertical thickness of the said arlns. The projecting parts of the armsor blades K are slotted horizontally, as shown in tig. 1. By thisconstruction and arrangement of the flasher-blades, the currents of milkcaused by each of the blades will be encountered and broken up by theothers, so as to throw the entire contents of the churn into a veryviolent agitation, bringing the butter in a very short time. l, v

What I claim as new, and desire to secure by Letters Patent, is

The combination of the removable frame B, sliding frame C, ratchet-barG, and pinion-wheel H, with each other, with the body A of the churn,and with the dasher-shaft I, substantially as herein shown anddescribed,

and for the purpose set forth.
